LATHE.

Bpeoiilcation of Letters Patent.

Patented May 11, 1915.

Application filed September 24, 1918. Serial No. 791,508.

the frame and movable parts as to render them simpler, more easilyadjusted and capable of facilitating a great variety of work with arelatively small number of tools, and to so construct and arrange thesaid parts that the lathe may be quickly and easily dismembered forshipping or other purposes and as easily assembled and set up for use.

The improvements consist in the construction, combination andarrangement of parts hereinafter described and claimed and illustratedin the accompanying drawings.

In the said drawings, Figure 1 is a side elevation of a lathe embodyingthe improvements. Fig. 2 is a plan of the same. Fig. 3 is a verticalsection of the tail-stock taken substantially on the line 3-3 of Fig. 1and looking in the direction indicated by the arrows in that figure.Fig. 4 is a vertical section of the slide-rest substantially on the line44 of Fig. 1 looking in the direction indicated by the arrows in thatfigure. Fig. 5 is a vertical section taken substantially on the line 55of Fig. 1 looking in the direction indicated bythe arrows in thatfigure.

Instead of having the ordinary groove and clamp in which the slide-restand tailstock move to and from the head-stock a pair of horizontalparallel bars A, A are provided, and on these bars the parts mentionedaswell as other parts when de-.

siredare slidably mounted by means of alined apertures in their basesthrough which the bar A passes, and movement of the slidable parts in avertical plane is prevented by the bar A upon which the opposite side ofthe bases rest.

The bars A and A are detachably mounted in the standards B and C, bybeing passed through bored bosses B and C respectively in the upper partthereof and held therein by means of set screws B and B in the formerand C and C in the latand are adap their bases resting on the bar A K,and the ter. the lathe and give it the desired rigidity a third bar A ispassed through the posts or standards near the bottom of each andsecuredby means of set screws B? and C. This third bar is in a verticalplane midway between the two upper bars and like the said upper barsmay-be removed when desired. The pulley D, mandrel E and head-stock arejournaled in the crotch F of the standard B ted to be driven by asuitable belt. The sllde-rest'G and the tail-stock H are mounted toslide on the bar A, as above stated, and have extensions G and H ofThese portions which rest upon the bar A are provided with adjustingscrews G and respectively whereby the said parts, and tools carriedthereby or resting'thereon may be tilted or canted so as to be 'held indi erent positions radially with respect to the the center I (see Fig.4), and in this manner the work on' the tools may be controlled with thegreatest accuracy and precision. The frame of the tail-stock is providedat its rear end with a plate J which enters the groove K of theinternally threaded sleeve said plate J is held against the frame bymeans of a clamp L, so that the spindle M may be moved backward andforward through the sleeve H by means of the screw M, or moved to aninoperative position by loosening the plate J and allowing it to dropsaid groove K. The with a vertical slot J downward movement. Tools ofvarious kinds may be inserted in the tail-stock and held therein by theset screw N. The sliderest and tail-stock may be fixed in any desiredposition longitudinally of the bars A,

plate J is provided whichpermits this A by means of the clamps G", H",and a- In order to strengthen the frame of opposite. Y

from engagement with the,

from the work by means of lever which has its'fulcrum in the outerupturned end of the bracket R mounted in the tailstock and movablelaterally therethrough,

but adapted to be fixed by means of the being facilitated by, moving thebracket R- outward so as to withdraw its upper end from the slot afterwhich the pin may be removed from the hole of the spindle.

It will be ap arent that a lathe constructed in accordance with theresent improvements is capable of a variety of adjustments and that agreat variety of work may be'done by manipulation of the parts withrelatively few tools. It will also be apparent that such a lathepossesses great advantages in that it is of simple, light and compactconstruction and may be quickly and easily dismembered and packed forshipping or other purposes and as easily assembled and setup for use.One of the advantages not hereinbefore specifically referred to is thatresulting from the arrangement whereby the bottom plates of the clampsby which the parts mounted on the bars A and A are securedmay be turnedso as to'pass between the bars and the said parts then turned to aposition in which they depend from the bar A and leave a space above'thesaid bars free and unobstructed, while at the same time the said partsare not disconnected and may be quickly restored to their normalposition. Other advantages will appear to those skilled in the art.

In the foregoing specification and in the 'claims various terms familiarto the art have been applied to some of the parts, as for instancetail-stock, and slide-rest. The parts referred to, however, differ inmany respects from those common in the art and are capable of performingfunctions not usually performed by the parts described by such terms. Itmust therefore be understood that these terms are used for convenienceof description and not with the intention of disclaimingany of the novelfeatures.

What I claim is:

1. In a device of the characterdescribed,

the combination of a plurality of standards,

a plurality of bars horizontally disposed mounted in said standards, atail-stock movement.

mounted on said bars to have free movement vertically with respect toone of them, and means for adjusting the limit of said 2. In a device ofthe character described, the combination of a plurality of standards, aplurality of bars horizontally disposed mounted in said standards, aslide-rest mounted in said bars and freely slidable to and fro thereonand means for moving the said slide-rest vertically and for maintainingit in different positions thereon, said means permitting free verticalmovement of the rest in one direction. w p

3. In a device of the character described,

the combination of a plurality of standards a plurality of barshorizontally disposed standards, and extends from one to the other, atail-stock mounted on said bars and means for movingthe said tail-stockvertically and for securing it in different vertical. positions thereon.

5. Ina device of the character described the combination of suitablestandards, a bar horizontally supported by said standards, a toolsupporting member mounted to slide freely to and from the head on saidbar, a second horizontal bar adjacent to the first and adapted toreceive and support a portion of the said tool supporting device, meansfor moving the said supported portion to and from the said last namedbar and for holding the same in different positions with respect to saidbar, said holding means permitting additional movement of the supportingdevice in one direction angular to the bar.
